Hello,

 I need to add programmatically Custom Attributes in RadComboBox

 i get an error on click button to get a value for custom Attributes

 this.LBL_MOVIE.Text = this.PCB_MOVIE.SelectedItem.Attributes["movie_p"]; 

Cause this.PCB_MOVIE.SelectedIndex is equals to -1

protected void PCB_MOVIE_ItemDataBound(object sender, RadComboBoxItemEventArgs e)
       {
           e.Item.Attributes.Add("movie_p","rocky");
       }

Hello,

The RadComboBox' SelectedIndex property will return -1 if none of its items is selected. If at that moment you use it to access an item in the ComboBox' items collection, for example:
string attr = RadComboBox1.Items[RadComboBox1.SelectedIndex].Attributes["movie_p"];
an ArgumentOutOfRangeException exception will be returned.
If an item is selected the SelectedIndex property will correctly return its index and you will be able to use the property's value.
